Filed: 1991-09-26
Abstract: An optical sensor (1) with an integrated optical arrangement has a waveguide (4) and at least one diffraction grating (5) arranged near this waveguide. Light can be coupled into the waveguide via the diffraction grating. Part of the light is dissipated by the waveguide in the reflection region of the diffraction grating below the beam angle for which the coupling conditions and thus the diffraction into the waveguide is fulfilled, so that below this angle a dark line (14) is produced whose position is evaluated. The measurement result is influenced by the effective refractive index. The latter, in turn, depends inter alia on the measurement substance (9). In order to avoid complicated adjusting devices for the coupled-in light beam (12), a convergent coupling-in beam of light rays (13) is provided which overlaps or includes the coupling-in light beam fitting the diffraction grating (5). As a result, the incident angle of the beam of light rays (13) is as far as possible uncritical, it being the case advantageously that any positional displacements that may occur have no disadvantageous influence on the measurement result. <IMAGE>

Abstract: A first-in, first-out (FIFO) memory includes flag generation circuitry which utilizes a write clock counter and a read clock counter to provide the number of write clock pulses received since the previous write reset signal and the number of read clock pulses received by the FIFO since the previous read reset signal. Specific flag values are user-programmable and are stored electronically as binary numbers in registers. The connection between individual subtractor circuits and individual comparator circuits for making a difference comparison is performed by a program select decoder which utilizes the difference output of the subtractor circuit and the flag program value. False flag information is filtered by a bi-stable de-glitch circuit which includes a delay path to emulate operation of the counter, subtractor and comparator. The magnitude comparator is programmed one count away from the desired flag transition point. The filtered flag output is updated at the onset of each blanking interval, thus making it representative of the current state of the FIFO.

Abstract: The cylindrical container's inner surface tester extracts image information about the opening portion and the deformation of the inner surface of a test cylindrical container through an image recognizing technique, and checks the circularity of the opening portion of the container. According to the image information, it specifies the position of a test cylindrical container as a predetermined position. Since it sequentially checks a series of cylindrical containers, the adjacent point between the containers must be identified. Then, the cylindrical container's inner surface tester identifies the adjacent point of cylindrical containers through calculations and logical operations according to the image information. Likewise, the cylindrical container's inner surface tester extracts a test area of an opening portion of an image of a test cylindrical container according to calculations and logical operations, and performs various processes such as determining the acceptability of the extracted white or black level of an image.

Abstract: A channel assignment system assigns channels to various cells by the optimal partitioning of the available radio frequencies into non-overlapping sets, the optimal grouping of co-user cells, and the best assignment of the former to the latter. The objective is the maximization of traffic handling capacity which, given the multitude of cells, is expressed as the maximization of a bottleneck capacity ratio. The  capacity rati o for a cell is defined as the ratio of the number of radio frequencies assigned to the cell over the number of radio frequencies needed to meet blocking probability requirements. The solution to attain an optimal non-regular channel assignment (460) is decomposed into two mathematical programs designated a Master Program (420) and a Subprogram (440). These are solved iteratively with assistance from a channel set augmentation technique (430) implemented between solutions of the Master and Subprogram.

Abstract: Frequency generators that may be programmed are utilized in a wide variety of applications. Typical applications include radio and television receivers and transmitters, and computer devices that must operate at different clock rates, or be compatible with systems that operate at different clock rates. The present technique provides for programmably generating a frequency. A ring oscillator (201, 202, 203) receives at least one operating voltage (V DD ) through a programmable array (204, 210, 216) of field effect transistors (205, 206, 211, 212, 217, 218). Digitally selecting a given set of the transistors provides a given operating current for the ring, which establishes the frequency of operation. In one embodiment, the technique is implemented in a CMOS integrated circuit. This technique provides for more rapid frequency changes in a low-power circuit than can be obtained with typical prior-art techniques (e.g., a phase-locked loop).

Abstract: A magnetic disk drive includes redundant data written at a plurality of out of phase angular locations to reduce the latency and enhance performance during a read operation. The loss of recording capacity is reduced by increasing the data density to achieve the same soft error rate standard required for single recording. Dual recording also allows different recording codes to be used at the duplicated locations to thereby have the more highly stressed code words occur at different locations in the data to further reduce the possibility of an error. The redundant recording can be used in one portion of the media and normal recording used in another media portion to enable selection of the recording technique in accordance with the type of data being stored. The size of the normal and redundant recording portions can be controlled by the format operation and the user of the disk drive can intervene to designate the size of the redundant and normal media recording portions effected during the format operation.

Abstract: A photosensitive optical body (23) is exposed by a diverging three-dimensional standing wave interference pattern generated by a holographic projector system. The projector system, using binary optics, creates a diverging lattice of hexagonal or square rod-like intensity maxima extending through the optical body. After the standing wave image is recorded and fixed, the optical body will contain a honeycomb-like grid or pattern that will cause either an absorption or a refractive index modulation effect on light that differs in incidence to the direction of normal propagation through the created channels to a focus or convergence point. This produces either a volume-absorption hologram or a volume-phase hologram (transmittance function modulated by the permittivity [index of refraction]) with such properties as depth of focus, high resolution, and a one-way (directional perspective) and anti-glare effect with reduced diffraction. Unique photosensitive aromatic diazo compounds which possess high thermal stability and soluble in non-polar solvents are provided. In the volume-absorption hologram, the compounds react with couplers within the optical body during development to form azo dye in the areas corresponding to destructive interference during exposure. While chiefly intended for use in eyeglass lenses, the optical body may also find use in telescopes, detectors, film and video cameras, and various other optical devices. The holographic projector system also affords a production method of writing highly-corrected peripheral as well as center-field mesh patterns on planar or non-planar surfaces.
